Filed: 1947-05-19
Abstract: 623,712. Vertical steam boilers. ANGUS, A. R. May 19, 1947, No. 13395. [Class 123(ii)] In a steam boiler pro vided with one or more inclined banks 1 of water tubes extending across the combustior chamber 2, the tubes o: each bank, preferably straight and of the same length, are expanded at both ends into hydrauli cally pressed plates ; which are riveted to the interior of the shell 4 of said chamber 2 so as to be removable through the latter. The tube banks are fitted with interdeck or other baffles 22, and the upper one may accommodate a superheater 23. Access to the tubes is afforded through openings 5 in the boiler outer shell 6, said openings being normally closed by removable covers 7, and also through holes 14 in which may be fitted soot-blowers. A feedwater supply valve 12 and a sludge blow-off cock 24 are mounted on the shell 6 at near the upper and lower ends thereof, and within the shell are provided a channel-shaped baffle, &c., 15, for directing the feedwater downwards to adjacent the lower end of the lowest tube bank, and opposed sludgeretaining lips 17 accessible through the openings 5. The boiler shown has a grate 18 for solid fuels, a fire door 19, ashpit 20, and one or more flues 8, but in a modification the boiler is heated by hot waste gases admitted to the lower end of the combustion chamber and is also fitted with an auxiliary oil burner. Instead of the convection superheater 23, a radiant heat superheater may be fitted, and the flue or flues 8 may be replaced by a plurality of vertical smoke tubes.

Abstract: 1,147,761. Laminated vehicle frame. PARBENFABRIKEN BAYER A.G. 25 March, 1966 [26 March, 1965], No. 13420/66. Heading B5N. A self-supporting underframe for a vehicle comprises two shells, firmly connected at the edges thereof, the space between the two shells being filled with a hard foam core produced in situ from an expandable reaction mixture, the density of the core exhibiting local variations in a direction perpendicular to the shells and in at least one other direction parallel to the shells. The shells may be of metal, plastics material which may be reinforced with glass fibres), e.g. polyvinyl chloride or plywood and the underframe may be of such shape as to provide a front section, engine and gear-box compartments, wheel compartments, instrument frame compartment, the lower surface of the vehicle compartment, fuel tank compartment, luggage compartment and tail section. The foam core may comprise a phenol-formaldehyde resin, an epoxy resin, polyurethane or polystyrene, the local variations in density being effected by roughening mechanically the inner surfaces of the shells, e.g. by sand-blowing and by subsequently coating them with an adhesive in which three-dimensional glass fibre or synthetic resin fleeces or flocked carrier material, e.g. jute are embedded or on to which fibres are electrostatically flocked. The underframe may be divided into separate compartments, e.g. by bulkheads of foam. Reinforcements, e.g. layers of fibres, torsion bristles, honeycombs, sleeves or gauzes, cables, conduits, pipes and instruments may be incorporated prior to formation of the core. The undersurface is preferably sprayed with an elastomer.

In a machine for operating on, e.g. welding, a peripheral zone within a tubular workpiece, a composite body A insertable within the workpiece 3, comprises three concentric tubular members 10, 5 and 16, the inner member 16 being rotatably mounted within the non- rotatable intermediate member 5 and carrying a tool B which is radially adjustable, and the outer member 10 being rotatable to operate centring means 13 for centring the body A in the workpiece 3. The tool B is an arc-welding torch pivotally mounted on the inner member 16 and movable radially by a link 26 actuated by a rod 29 from the exterior of the tube 3. The rod 29 also carries a stop 32 for locating the machine endwise. The inner tube 16 rotatably carries a centring head 18 having pins 20 extendable by gears 21 actuated by a fluidpressure piston 22 to engage the interior of a tube 1 to be welded to the tube 3. The intermediate member 5 is fixed to a plate 6 having sleeves 7 axially engaging over pins 8 secured to the work. Rotation of the outer member 10 by a hand wheel 15 moves pegs 13 along a groove having a sloping base in the intermediate member 5 so forcing the pegs 13 against the tube 1 and centring the body A. The inner member 16 and torch B are rotated by a motor 35. Gas, e.g. argon, water and welding wire 43 are fed through the inner member 16 to the torch B. A lamp 41 illuminates the portion being welded which is viewed by an optical system 33. Specification 946,256 is referred to.

Filed: 1974-03-27
Abstract: 1431747 Carburizing high alloy steels BOEING CO 27 March 1974 [10 April 1973] 13604/74 Headings C7A and C7U To prevent the formation of a low temperature 3, passive metal oxide film on the surface of high alloy steels after cleaning prior to case-hardening, which prevents uniform carburization, the steel is subjected to a high temperature oxidation treatment at at least 1000‹F to form a high temperature oxide, which is not resistant to carburization. Examples of martensitic steels suitable for the process i.e. Vasco 2, modified Vasco +2, modified H11 tool steels and 416 stainless steels are given, and are treated by conventional grit blasting, followed by oxidizing at about 1800 for ¢-4 hours and cooling. The high temperature oxide thus formed is stable and the steel may be left for extended periods prior to case hardening without detriment. The high temperature oxidized steel may be carburized in a conventional manner at 840-1010‹C for 6-30 hours to produce any desired case thickness and subsequently heattreated to optimize its properties.

Title: Purification of sugar solutions
IPC: C13B20/14
Filed: 1956-05-03
Abstract: Aqueous sugar solutions containing a solute, e.g. potassium aconitate, of ionization constant at least 5 X 10-2 are fed to displace water from a water-immersed bed of a highly ionized ion-exchange resin of gel water content 50-90 per cent by volume, and then water is fed to the bed in order to obtain a fraction containing a major portion of the highly ionized solute and then a fraction containing a major portion of the sugar.  The volume of sugar solution is preferably not greater than the volume of water absorbed within the resin particles, and the volume of water fed is preferably at least that of the absorbed water.  Solution temperatures between 25 DEG  and 80 DEG  C. are suitable.  The resins used are sufficiently highly ionized that a 10 g. portion of a cation-exchange resin added to 100 ml. of a 0.1 n. sodium chloride solution reduces the pH to less than 3 and an anion exchange resin under the same conditions produces a pH greater than 11.  Examples of the resins are the sodium or potassium salt of a nuclear sulphonated copolymer of 93.5 per cent styrene, 2.5 per cent ethylvinylbenzene and 4 per cent divinylbenzene and a quaternary amino-methyl nuclear substituted copolymer from styrene, ethylvinylbenzene and divinylbenzene in similar proportions.

Abstract: 685,599. Phase changing. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. June 18, 1951 [July 12, 1950], No. 14404/51. Class 38 (ii). A static phase balancer for interconnecting a three-phase supply circuit 10 and a single phase circuit 15 supplying a load such as a tractor system, comprises two transformers 11, 12 in Scott connection with inductance 17 and capacitance 18 connected respectively to the two transformers, the secondary windings 26, 31 of which supply the load in series. Two of the three input phases 23, 25 are respectively connected to ends of primary windings 21, 22 of the transformers. The third input phase 24 and the other end of winding 21 are conconnected to taps on winding 22 through conventional tap changing gear 38, 36 operated by a motor 39 controlled by a voltage responsive relay 44 of the balanced beam type which has coils 45, 46 connected respectively across input phases 23, 24 and 23, 25. The control is such that the voltages across these pairs of phase are restored to equality, and the voltages across phases I and II to a 90 degree phase difference, after variation therefrom because of load unbalance. Inductor 17 and capacitor 18 are respectively connected across the transformer secondary windings 31 and tertiary winding 61 through tap changing gear 52, 63 driven by motors 59, 65 under the control of power factor relays 33, 28, whereby the power factors of phases I and II may be controlled. It is shown that for unity power factors the capacitor and inductor must each have a KVA value equal to one half that of the load. The load power factor may be controlled by a capacitor 73.
